terminal).

3 Device detection fails. • Under "Settings / Misc", the device detection mode
is set incorrectly (see section 8.4. 1 "Narrowing the
Scope of Device Detection" (Page 50)).
• The PC interface's baud rate does not match that of
the Sunny Boy Control.
• The wrong transfer medium was selected.
• Sunny Boy Control is not ready for reception.
• With the transfer medium RS485, it may be the case
that in the extended properties of the serial port used
for the Sunny Boy Control, FIFO has not been
deactivated.

in operation. • Data cable between PC and SBC interrupted.
5 "Cannot open file." • A data file (SDX_XXXX.xls) is already open in
another application (e.g. Excel) upon data transfer.
Close the respective application, and start the
transfer anew.
6 "The new device type is
unknown because the device is
unreachable." • At present, communication with the device is not
possible. Possibly, the wrong serial number was
entered, or the device is not switched on.
